PROTECTIVE BOOK COVER' Application filed June 1,

This invention relates to improvements in book covers and has particular reference to supplemental covers used in affording protection to the permanent bindings of books.

As a rule, a book comes from the publisher provided with a temporary protective covering which consists usually of a single sheet of paper of a width equal to the length of the book and sufliciently long to extend about the outer surface of the permanent cover and have its ends turned inwardly over .the side edges of the same. Protective covers of this character are excellent for the purpose for which they were designed and that is to afford protection for the permanent binding during the-time it is on the book sellers shelf. For further use however, it is far too fragile and has the great objection of continually slipping out of place. Therefore, if the permanent cover of a book is to be protected while being handled by readers, it follows that the slip cover just described will of necessity, have to be discarded and a more efiicient one substituted therefon- I s t It is then the object of this invention to provide a protective'covering of the character hereinafter described, which is applicable to books of various sizes and which is very easily applied and removed without damage either to itself or the book binding.

A further object of the invention is to con struct a protective covering which is proof against moisture on the one slde and of a soft texture on the side placed next to the bookbinding.

I accompllsn these ObJGCtS by means of a construction for a protective covering comprising superimposed layers of fabric mate-l rial of rectangular shape, at the corners of which are interposed angle pieces-of ductile metal capable of maintaining any shape in which they are bent, said cover being suitably folded about the permanent binding and fixed in position by merely binding the metal inserts with the folds of the fabric to overlie the edges of the book cover at its corners.

One embodiment of the invention is described in the following specification and claims and illustratively exemplified in the accompanying drawings, in which, Figure 1 1929. Serial 'No. 367,753.

is a perspective view of a book in partly open position with a protective covering being applied thereto; Figure 2 is a plan view of the protective covering showing the layers of fabric at one corner laid back to disclose the metal angle piece; Figure 3 is a substantially sectional view of the protective cover taken on lines 3-3 of Figure 2; and Figure 4 is a perspective view of one of the metal corner inserts.

1 Referring to the drawings, 10 denotes a book having the usual permanent cover portions 11, and 12 the protective covering therefor.

'The protective covering 12 according to the present invention, comprises a rectangular member made up of two layers of fabric, one thereof, being the inside or lining 13, is of a thin grade of felting, while the outside layer 14 is of a coated material which gives it a smooth outer surface of moisture-proof texture,;and a rougher inner. surface capable of holding an adhesive used to affix the felt terposed between the layers 13 and 1 1 at each corner, each arm of the metal strip being arranged substantially parallel to an edge ofthe member at the corner, as illustrated in Figure 2. The metal of the strip fastener 15 is of a grade which allows bends to be made repeatedly at'substantially the same place without causing the metal to crystalize and which after being bent, retains its shape until further manipulation is necessary. In order to protect the permanent book cover from possible damage, should the metal strip part and pierce the felt layer 13, I provide a piece of tough paper 16 which is interposedvbetween the felt layer13andthe metal strip 15 and which is coated with an adhesive on the side overlying the metal, so as to secure the same in position.

It has been described that the protective covering is rectangularly shaped and of a size which leaves a marginal portion entirely around the cover of the book being covered, when the latter is wide open. The back of the book is placed in position between tne loo longer sides and at the center of the covering member 12. Cuts 17 are made in the marginal portions of the covering on opposite sides of the center line underlying the back of the book, which cuts permit the intermediate marginal portions to be folded over on the inner side of the'backportion of the protec tive covering, to bring the same down to a length equal to the height of the book itself. 7 10 To apply the protective covering 12, the book is placed over the innerfelt layer 13 as illustrated in dotted lines in Figure 2, andv the triangular corners of the covering between the ends of the arms of the metal pieces 5 15 are folded down over the corners of the permanent book covering 11. Thereafter, each. of the marginal portions including the outer ends of the arms of the metal strips 15 is folded over its respective edge of the cover as illustrated on the left side of Figure 1. The metal fastener strips 15 having been bent with the material. of the covering over the edgesofthebook cover 11, hold the protective covering 12 in place about the book. To remove the protective covering requires merely, the unfolding of the metal fasteners 15. to release the cover portions of the book.

Having now described my invention and the manner in which the same may be applied, what I claim and desire to secure by Letters. Patent, is:

1.. In combination, a protective book covering of rectangular shape and square corners and comprising superimposed layers of fabric material, andan angular fastening member comprising a narrow band of flexible metal interposed ateacn corner between said layers with its sides forming; a rectangle with the corner of the covering at. the corner, the

arms of the metal being folded with the covering to secure. the latter to the book.

2. A. protective book covering as claimed in claim 5, including a reenforcing layer of material: arranged over each metal fastening member and between it and the overlying layer of fabric.v v

In testimony whereof I afiix my signature.
